In his absence, it is highly expected that Mitchell Marsh could be promoted to open the inning with David Warner, as he performed exceptionally well at the top of the order in the series against India. Australia will take on India on October 8 in the opening match of the tournament in Chennai.However, there is no official word from Cricket Australia (CA) regarding the replacement of the left-handed batter, but as per the reports, Australian selectors might consider the in-form batter Marnus Labuschagne to add in the squad.The final date to make changes in the squad is September 28, after which any changes will require approval from International Cricket Council (ICC) officials.
